Abstract

The rate constant of the heterogeneous electron transfer from a platinum electrode to aromatic disulfides is low, whereas the homogeneous electron transfer from suitable aromatic anion radicals is much faster. Anion radicals of such aromatic compounds can thus be generated electrochemically at potentials more negative than the normal standard reduction potential of the disulfide, but less negative than its observed reduction potential. An attempt is made to estimate E~0~ of the aromatic disulfides from the rates of the homogeneous electron transfer from a number of donors and the reversible redox potential of these donors.

## Abstract The electron transfer between excited‐state 9,10‐anthracenedione (325 nm) and sodium tetraphenylborate (tetraphenylboron sodium) in acetonitrile solution is shown to form the radical anion of 9,10‐anthracenedione together with the BPh radical. The latter is known to decompose to bipheny
